> Ok to make sure I get this right:
> - we enable deferred log flush by default
> - we set flushlogentries=1
> Also since 10 seconds is kind of a huge window I propose that:
> - we set optionalLogFlush=1000
> which is the MySQL default. We also have to update the wiki (there's
> already an entry on deferred log flush) by adding the configuration of
> flushlogentries.
